+Windows MSVC support!

+- The makefile target `build-win` now builds for Windows MSVC

+- `install-dev` is now the default goal in the makefile

+- The integration tests also don't use hardcoded *NIX paths anymore
+- `check_empty_config()` checks for curse_project now, this was a bug fixed by [SolidTux](https://github.com/SolidTux) in [PR #2](https://github.com/theRookieCoder/ferium/pull/2)
